The number I watch most closely at The Study Mill isn't signups. It's how many people answer their first question, because that's the moment the app does what it's for. Building a study set is setting the table. Answering a question is eating.
So I looked at everyone who signed up over 30 days in September and October 2026. Fifty-two students.
Forty of them uploaded a lecture and built a full study set: lessons, flashcards, a quiz. That's the hard part, I thought. They'd done the effort. Then only 20 answered a single question. Half the people who'd done all the work walked away just before the payoff.
Where they went
Because the app records what people tap (not what they write), I could follow each person's first session step by step. A few patterns jumped out.
1. We interrupted them at exactly the wrong moment. The second a study set finished building, the app asked: "When's your exam?" Reasonable question. But answering it took people to a revision planner, a whole different screen, before they'd studied anything. We'd built the table and then walked them out of the room.
2. The first thing on the page needed headphones and 12 minutes. Our flagship feature is Walk & Learn, an audio lesson, and it sat at the top of every week. Lots of new students opened it. Fewer had headphones in, or 12 spare minutes, right then.
3. Most of them only came once. Of the people who never answered a question, about three in four never came back for a second visit. If the first session doesn't land, there usually isn't another.
4. Half our welcome emails were never sent. People who signed up with email got a "confirm your address" message, and our welcome email waited until they clicked it. Four out of five never did, so most never heard from us at all.
None of these are dramatic bugs. Each one is a reasonable decision on its own. Together they added up to a first session that ended one step short.
What we changed
The first lesson comes first. If you've never answered a question, your first week now opens with three quick multiple-choice questions from your own notes, right at the top. One tap each. Every answer counts as soon as you tap it, so even one is a start.
The exam date question waits. It now comes after that first lesson, not before it.
One welcome email that does both jobs. The welcome email now includes the confirm link, and its main button is "Open my first lesson". Clicking it confirms your address and drops you into your first lesson.
We also took the chance to make the questions themselves harder to game, after a student pointed out that the right answer was too obvious. That story is here.
Why I'm sharing this
Partly because it's useful if you build things: the gap between "did the setup" and "got the value" is where products quietly lose people, and you can't see it unless you look at what people actually do.
But mostly because it's useful if you study. The same thing happens to you, without any app. You make the flashcards, or you download the past paper, or you set up the perfect Notion page, and that feels like progress. It's the table. The learning only starts when you answer the first question. Why answering beats rereading.
If you've got a study set you built and never used, open it and answer one question. That's the whole trick.
I'll update this post with how the changes did once there's enough data to say honestly.
Method: every account created in the 30 days to 11 October 2026, with our own and automated test accounts excluded. "Built a study set" means at least one week was built from uploaded material. "Answered a question" means at least one question answered anywhere in the app. For this we looked only at which screens and buttons were used, not at anyone's notes or answers.
